COIN-CONTROLLED MECHANISM.

Application filed December 30, 1920. Serial No. 434,032.

To all whom it may concern:

Be it known that I, Roscoe ROYAL, a citizen of the; United States,residing at Chicago, county of Cook, and State of Illinois, haveinvented new and useful Improvements in Coin-Controlled Mechanism, ofwhich the ningto the coin box.

following is a specification.

My invention relates to coin controlled mechanism in which forcing acoin through the coin slot assists the parts in closing an electriccircuit for driving an electric motor such as a fan motor when apredetermined number of'revolutions of the shaft of the motor will inturn be assisted by suitable gearing to open the electric circuit inrestorin; the coin mechanism to normal.

. The object of m invention is: (a) to furnish an improve means ofcollecting a coin for use of an electric fan for a predetermined time ornumber of revolutions of fan; (b) to provide for collecting a number ofcoins successively at one time for extended use of the aforesaid fanmotor for a multiple of the predetermined time in accordance with thenumber of coins dropped up to a given limit, say ten; and

(c) not to re ister further coins till part or all of the predeterminedtime has been worked out.

A form in which my invention may be practiced is illustrated in theaccompanying drawings in which Fig. 1 represents a general workingoutlay of the parts. Fig. 2 shows an arrangement of parts to close thecircuit of the motor.

Referring to Fig. 1: 4 represents the frame of the coin box, 3represents the frame of the gear casing at the motor shaft, 6 represents a flexible shaft or wire and its flexible housing 7 runningbetween the two frames. Conductors 8 and 9 to complete the circuit ofmotor M also are shown run- I At .V is shown the last deposited coin inplace. The form of coin box I have preferred to illustrate is such thatthe last coin deposited is held in place forview as to quality ifdes1redthe preceding coin in each instance being used to operate thecircuit closer by the aid of the succeeding coin as will be shown. AtPisa push button projecting through the top of the box normally heldupward by rod 14 working through slot 17- and pressure of spring 15against stop 16; Push button P is arranged to be pushed downward thelength of the coin used so when the first coin is passed through slot Sinto continuation of slot T it will drop as far as permitted by spring45. Application of pressure from push button P will force the coin pastspring 45 into position at V ready ,to engage with projectiug arm 19. Asbefore mentioned, one coin is retained in the coin box so the mechanismis operated not by the first coin but by every coin thereafter. The nextcoin dropped in slot S represented dotted at 5 will obviously whenforced downward by push button P transmit a downward movement to coin Vwhich in passing to coin box will momentarily push the lower end ofprojecting arm 19 aside from obstructing the coin slot T. The arm 19pivot- .ed to the frame t at 20 and coupled at its upper end to arm 23carrying the tooth 24 will when moved against tension of spring 22 outof normal position with lower end obstructing the coin slot T, changethe position momentarily of the arm 19, arm 23 and tooth 24 restingagainst stop 25 to locations represented by dotted lines so that tooth 21 is ready to engage a tooth of wheel 10. On forcing the coin V past thelower end of projecting arm 19 and into the coin box 4:7, arm 19 tendsto return to normal, relieving theipull from arm 23 so spring 22 tendingto retract arm 23 causes tooth 24 to engage a tooth of wheel 10 and movewheel 10 one tooth in direction of arrow, placing a succeeding toothunder lower pellet of escapement 26 under pressure of spring 27 and arm23 and tooth 24 return to normal against stop 25. This same movement ofwheel 10 moves insulation 31 attached thereto under spring 12 bringingit into contact with spring 11 closing the circuit of motor M throughrheostat R, conductor 9, spring 11, spring 12, conductor 8 to the mains.

The action of springs 11 and 12 in the circuit closing operation is alsoshown in Fig. 2. r

As the motor runs, shaft 33 which is the motor shaft and carries thefan, revolves, turning screw 3 f meshed with saw tooth wheel 35 runningon pin 37 and carrying pinion 36 in mesh with wheel 38, revolving on pin4&1 carrying hub 39 and cam 40.

fan a predetermined interval. Pivoted to frame 3 at 43 is arm 41pressing against hub 39 ready to engage with cam 40. At the upper end ofarm 41 wire 6 is attached at eyelet 42. At its further end wire 6 isattached to double escapement 26 by spring 28. Spring 29 applies tension'to draw wheel 10 to normal. As wheel 38 revolves cam is brought aboutto force arm 41 outward, pulling wire 6 applying tension on spring 28 topull upper pellet of 26 to engage with wheel 10, allowing the escapementof tooth by relieving the lower pellet from engagement with wheel 10. Onfurther revolution of'wheel 38 the cam 40 allows arm 41 to return torest against hub 39, allowing wire 6 to move back relieving tensionon'spring 28 which in turn allows spring 27 to draw back doubleescapement 26 relieving upper pellet thereon from engagement with wheel10 and allowing the latter to drop back another half tooth. Inthisinstance the wheel 10 is at normal, the projection 30 thereontouching stop pin 49. The insulation '31 also moves from under spring12, breaking the circuit of the motor.

It is obvious from the drawing that the wheel 10 may be advanced areasonable number of steps by the use of successive coins till the space50 comes to double escapement 26 when no further advance will bepossible regardless of how many coins are deposited.

I do not limit myself to the details as set forth in this description asmany changes could be made in the apparatus and arrangement withoutdeparting from the spirit of the invention.
